a 4 W1 V or tubular form with v hipge -eyglegs or bearings. It is, therefore, necessary to stamp? oficut irreg lilarfpiece of metal from the original sheet thereby ga sir g eonsiderable Waste. It jidfile that these hinge bearingsf be liickelgplated. Where the hinge bearings" "are'unte'grally formed with the clamping members, they could not I very well be separately nickel plated; Consequently, the whole clamping member had costly.

the aforementioned defects in the provision of a structure wherein the clamping members and hinge bearings are separately formed, thereby avoiding the costly waste, and inwhich the hin e bearings may be nickel plated before tfiey are attached to 40 the clamping members, and in which the clamping members may be formed from a rectangular sheet of metal into a tubular or elliptical form, bringing the ends together and spot-welding or securing the hinge eyelets over the meeting edges.

The invention comprises the novel structure and combinations hereinafter described fined in the appended claims.

I am awarethat numerous details of conples of this invention and I therefore do not purpose limiting the patent granted, otherwise than necessitated by the prior art.

I claim as my invention:

1. In a loose leaf binder, a hollow clamping member formed from a rectangular sheet of metal having its longitudinal edges brought into juxtaposition, and hinge bearings having oppositely extending attaching flanges welded exteriorly of said member over said edges.

2. A clamping member for a loose leaf binder, comprising an elliptical and hollow metal member having longitudinally extending meeting edges, and hinge eyelets united with said member over said meeting edges for the purpose set forth.

3. A clamping member for a loose leaf binder, comprising a substantially elliptical hollow metal member having longitudinally extending meeting edges. and hinge eyelets having means exteriorly spanning said meeting edges and welded to said member.

4. A clamping member for loose leaf binders, comprising a hollow elliptical metal member formed from a rectangular sheet of metal having meeting edges and hinge eyelets welded over said juncture of said meeting edges.

5. A clamping memberfor a loose leaf binder, comprising a hollow tubular element formed from a rectangular sheet of metal having its longitudinal edges in juxtaposition, and members attached exteriorly of said tubular element and extending over said edges for retaining the same together,

said members forming a connection for a binder cover.

56'. A' clamping member for loose lea-f binders, comprising a flattened tubular member, and binge bearings having oppositely extending attaching flanges welded to the exterior of said member, said bearing members projecting in line with the major axis of the tubular member.

7. A clamping member for loose leaf binders, comprising a tubular member flattened upon its sides to afford a broad clamping surface, and hinge eyelets welded exteriorly of said member, the axis of said eyelets being substantially in the central longitudinal plane of said member, and said hinge eyelets embracing the edge of said member within the planes of its flattened sides.

8. A clamping member for loose leaf binders, comprising a tubular member flattened upon its sides to aflford a broad clamping surface and hinge eyelets welded exteriorly of one edge of said member, the axis of said eyelets being substantially in the central longitudinal plane of said member, and said hinge eyelets having diverging attaching means embracingsaid'member and subscribing witnesses.
